SEPARATOR MECHANISM FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 498,341, dated May 30,1893.

Application filed February 10, 1893 1 Serial No. 461,734. .(No model.)

To all whom it may concern:

Be it known that I, OHANNING WHITAKER, a citizen of the United States,residing at Tyngsborough, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inSeparator Mechanisms for Ring-Spinning Frames, of which the following isa specification, reference being had therein to the accompanyingdrawlngs.

The invention relates to separator-mechanisms of the class in which theseparators are applied to a rail, rod, or shaft which is mounted onsupports provided therefor on vertical rods, termed separator-rods, towhich is communicated a vertical reciprocating movement resembling thatwhich is communicated to the lifting-rods which support the ring-railwith its rings.

More particularly, the invention relates to the supportsor sockets inwhich are formed the bearings for the journals or pivots of theseparator-rail, rod, or shaft, to the bearings themselves, and to thestop-devices which are provided for the purpose of determining thelimits of the rotation of the separator-rail, rod, or shaft.

One object of the invention is to provide in simple and convenientmanner for enabling the traverse of the separator-rail and separators tobe shifted or translated vertically as may be required from time to timein practice, without the extent of such traverse being altered.

Another object of the invention is to provide an improved constructionof bearings and stop-devices whereby the separator-rail and separatorsshall be sustained conveniently and securely in proper position in thering-spinning frame to which the devices are applied, and which, whilepermitting the separators to be turned from their lowered and working oroperative position between the spindles to their raised and idle orinoperative position remote from the spindle, when required, also shallpermit the separator-rail and separators to be taken directly from thesupports and from the machine at any time while the separators standundisturbed in the position occupied by them when at work, or withouthaving been moved to a material extent from such normal position,whereby it shall be rendered unnecessary, to provide for thedisengagement of the rail from its supports by first turning theseparators into their raised or idle position as sometimes has beennecessary heretofore in order to unlock the rail so that it may beraised.

The invention consists in certain features of novel and improvedconstruction, and in certain novel and useful arrangements andcombinations of parts, all as is hereinafter set forth fully, and itfirst will be described with reference to the accompanying drawings, andthen will be particularly pointed out and clearly defined in theclaimsat the close of this specification.

In the drawings, Figure 1 is a view in side elevation of the upper endof the vertical rod which is termed the separator-rod, and the socketwhich is mounted on the said end and provided with a bearing for the"journal or pivot of the separator-rail. Fig. 2 is a view of the sameparts in rear elevation, or from the left-hand side in Fig. 1. Fig. 3 isa view in vertical section on the dotted line 3-3 in Fig. 2. Fig. 4 is aview in horizontal section on the line 4-4= in Fig. 1. Fig. 5 is a viewin plan of the stop-collar which is mounted on the separator railadjacent to the socket shown in ,the preceding figures, and is providedwith stops that engage with the front and rear sides ofthe said socketin order that the rocking movement of the separator-rail may be limitedin extent. Fig. 6 is a view of the said stop-collar inside elevation.Fig. 7 is a view in side elevation, withthe separatorrail in section,representing the upper part of the socket shown in Figs. 1 to 3, theseparatorrail mounted in the bearing in such socket, and the stop-collarand a separator.

mounted on the said rail, the blade of the separator being broken away.Fig. 8 is a view in plan of the parts which are shown in Fig. 7. Figs.9, 10, 11 and 12, are views illustrating modified forms of socket. Figs.13 and 14 are views showing in plan and in side elevation a modifiedform of stop-collar. Fig. .15 is a view corresponding in character withFig. 7, but showing the form of socket which is represented in Figs. 9and 10 and the form of stop-collar which is shown in Figs. 13 and 14.Fig. 16 is a view in plan of the parts which are shown in Fig. 15.

At 1 in Figs. 7, 8, 15 and 16 is shown part of a separator-rail, at 2part of the blade of a separator, at 3 the hub to which the said blade1s attached, the said hub fitting the separatorrail as usual, at- 4 theclamping screw passing through a threaded hole in the hub and takinghearing at its end against the surface of the separator-rail, whereby toclamp the separator in place upon the separator-rail, at 5 the socketcontaining the bearing 6 which receives the journal of theseparator-rail, at 7 the stop-collar fitted upon the separator-rail andprovided with the stops 8 and 9, and at 10 the clamping-screw passingthrough a threaded hole in the collar and taking bearing at its endagainst the surface of the separator-rail to clamp the collar in placeupon the separator-rail. The stop 8 comes to rest upon a portion of thesocket 5 at the front of the latter when the separators have been swungforward into their working or operative position,which is represented bythe full lines of Figs. 7 and 15, and thereby arrests the rotation ofthe separator-rail and separators in that direction. The stop 9 comes torest upon a portion of the said socket at the rear of the latter whenthe separators have been swung upward and rearward into the idleposition which is indicated by the dotted l nes 1n Fig. 15, and therebyarrests the rotation of l the separator-rail and separators in j thereverse direction.

The separator-rod, which has the socket 5 mounted upon its upper end andis actuated as hereinbefore stated for the purpose of moving theseparators up and down, is shown in Figs. 1, 2, 3, 1,9, 10, 11, and 12,at 11.

As a simple and convenient means of setting the separator-rail andseparators at any desired height, and thereby varying or shiftingvertically as may be required the path traversed by the said parts intheir np-anddown movement, I mount and secure the socket 5 containingthe bearing for the journal or pivot of the separator-rail upon theupper end of the separator-rod 11 in such manner as to enable theposition of the said socket to be adjusted vertically upon the said rod.This adjustment of the socket upon the separator-rod may be relied uponfor the purpose stated, to the exclusion of such expedients asadjustable actuating mechanism, and an adjustable foot for theseparator-rod. Figs. 1, 2, 3, 4, 9, 10, 11 and 12, show a simple andpractical means for connecting the socket to the separator-rod in anadjustable manner. In these figures the interior of the socket,throughout the greater part of the length of the socket, is fitted forthe entrance of the end of the separator-rod, and the socket is held indesired position upon the said end by suitable clamping means which willenable the socket to be held at any selected point, as, for instance, bythe clamping-screw 12, which is fitted to a threaded hole in the lowerend of the socket and takes bearing against the surface of theseparator-rod.

Heretofore, the bearings for the journals or pivots of theseparator-rail, when made open and fitted to permit the separatoraail tobe lifted out of the same when it is desired to remove theseparator-rail from its supports, have been so combined with thestop-devices for determining the opposite limits of the retation of theseparator-rail in the bearings as that the said stop-devices act aslocking-devices and serve to hold the separator-rail from being movedout of the bearings until after the separators have been thrown out oftheir working position between the spindles backward and upward to theiridle position. I render it' unnecessary to throw back the separatorsinto their idle position, in order to unlock the separator-rail fromitssupports, by the construction and arrangement of the parts which I amabout to describe, which construction and arrangement, moreover, whilepermitting the separator-rail to be re moved directly from thebearing-supports and from the machine at any time while the sepa ratorsremain undisturbed in the position occupied by them when at work, orwithout their having been moved to a material extent from such position,also retains the separatorrail and separators firmly and securely inplace while the separators occupy their working position. i

To facilitate the application and removal of the separator-rail, I formthe socket 5 with an open bearing 6, as shown in the drawings, the saidbearing being without obstruction to interfere with the free movement ofthe journal of the rail while such journal is being removed from thehearing or replaced. The stop 8 provided on the stop-collar 7 takeshearing against a rest13 on the front side of the socket 5, which resthas its surface parallel with the rear side of the adjacent wall of thebearing, and is without any locking. projection or obstruction above oradjacent thereto to interfere with the said step 8 while theseparator-rail and connected parts are being removed. This permits theseparatom'ail to be taken from the bearing in the support by ITO intoclosecontact with the forward side of the to overhang the rail-journal alittle and place the upper portion of itsinteriorsurface more nearly ina plane at right angles to the plane of the lateral pressure which istransmitted through the rail-journah In, these figures, also, the rearwall 16 of the bearing isinclined in the same direction as the frontwallin order to facilitate the entrance of the railjournal. In the caseof the form of socket which isshown in Figs. 11 and 12, both walls ofthe bearing aremade vertical, for in these figures the arrangement,relations, as, of the rest 13 are such as to cause the lateral thrust tobe communicated to therail-journal more nearly in a horizontal plane. InFigs. 1,-- 2 and 3, the stop 8 takesits seat at a point helowthe seatfor the rail-journal and at a less distance in a horizontal directionfrom the axis of the rail-journal than in Figs. 9, 10,-11 and 12. InFigs. 9 and 10, thewrest 13 is inclined forwardly and I downwardly, and,as

I will be understood from Fig. 15, the tendency ot' the inclined surfaceis in part to crowd somewhat the stop and rail-journal in the directionof the inclination thereof. In Figs. 11 and 12 the rest 13 is verticaland located in advance of the said bearing.

A slight difference in form exists between. the stop-collar representedin Figs. 5 and 6,v which is intended for use in connection with thesocket represented-in Figs. 1, 2 and 3, and the stop-collarrepresentedin Figs. 13 and 14, which is intended for use in connectionwith the sockets represented in Figs. 9, 10, 11 and 12. In the former,the arms carrying the stopsS, 9, are made more nearly inline with eachother than in the latter,.in view of the fact that the contact-point onthe rest 13 in Figs. 1, 2 and 3, is lower than in the other figuresandnearer to the axis of the rail-journal. The stop 9 strikes against thesurface 17 at the rear side of the socket, to arrest the movement of theparts when the separators have been thrown back to their idle or inop:erative position. As will be observed, the surfaces 13, 17, are formedas narrow projecting parts of the sockets, they being located atmidwidth of the sockets and of semi-cy-. lindrical outline wherethestops touch them. When the separators are-intheir usual operativeposition the stopS presses against the narrow projecting rest 13. whileat the same time the journal of the separator-rail presses against theinterior of the bearing of the separator-rail socket. From this itresults that if the separator-rail socket should, from any accidentalcause, become slightly turned on its axis, the pressure of the stop uponthe narrow projection, and the pressure of the separator-rail journalagainst the interior of. the hearing, will restore the socket-bearing toparallelism with the separator-rail. Preferably, the face of the stopwhich bears against the narrow projecting rest is made of a cylindricalcurve, such curve forming part of a cylinder of small diameter which isparallel to the axis of the separator-rail.

I do not lay claim broadly herein to the;

combination of the separatorrail, and a stop moving in unison therewith,or carried by a collar mounted on the separator-rail,-ofa supportprovided with an open bearing for the rail-journal and also with a restwithout ob-' struction to interfere with the stop while the rail isbeingremoved, for this is not of my invention. Nor do I claim broadly hereinthe like combination having the rest located on ,the front portion ofthe support, or. the sup- 2. The combination with the separatorrrail, v

and the Separator-rod, of the socket formed Withja bearing forthereception of the rail andsliding vertically upon the rod, and theclamping-screw for securing the socket in the desired position ofvertical adjustment, sub:- stantially as; described.

3. Thecombinationwith the separators, .the separator-rail, and a piececontaining a bearing in which the rail is free to rock or turn, of thecollarmounted upon the-rail and provided with stops' projectingtooppostte sides of the bearing-piece into, positionto contact with thefront and rear of the latter and' therebyarrest the rail at the oppositeextremes of its rocking movement, substantially as described.

4. The combination with the separators,'

the separator-rail,-and the collar. mounted thereon having a stop, of abearing support constructedto permit the separator-rail to be removedtherefrom unobstructedly before the separators have beenturned out oftheir-operative position, it having the open bearing from which therail-journalmay be removed directly and-also therest on the frontthereof. without obstruction to interfere with the stop while the railis being removed, substantially as described.

The combination with the separators, the separator -rail, and acollar. mounted thereon provided with astop, of a support constructed topermit the rail-journal to be removed therefrom unobstructedly beforethe separators have been turned out of their op-1 erativeposition,ithaving the open bearing withthe front ,wall thereof slightlyinclinedrearwardly and from which the rail-journal. may be removeddirectly, and also on its-front portion a surfacewithout obstruction toin-v terferewith the stop while the latter isbeing removed,substantially as described.
